Unable to transcode a CMYK jpeg to jxl

[leuk0cyte]

Describe the bug
When I do a batch jpeg transcoding, some of these images in CMYK color space cannot be transcoded

To Reproduce

cjxl .\1.jpg 1.jxl
JPEG XL encoder v0.10.2 e148959 [AVX2,SSE2]
Note: Implicit-default for JPEG is lossless-transcoding. To silence this message, set --lossless_jpeg=(1|0).
Encoding [JPEG, lossless transcode, effort: 7]
Error while decoding the JPEG image. It may be corrupt (e.g. truncated) or of an unsupported type (e.g. CMYK).
EncodeImageJXL() failed.

cjxl .\1.jpg 1.jxl --lossless_jpeg=0 -d 1 -v -v -v -v
JPEG XL encoder v0.10.2 e148959 [AVX2,SSE2]
Getting pixel data failed.

Expected behavior
Images are correctly transcoded. Provide more effective information in case of an error occurred.
